SPINNING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 638,254, dated December 5, 1899.

Application filed March 31, 1899. Serial No. 711,301. (No model.)

T0 on whom it may concern:

Be it known that I, Aueusrn LEPOUTRE, a citizen of the Republic of France, residing at Roubaix, in the Department of N 0rd, France, have invented certain new and useful Improvements in Spinning-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

In the manufacture of textile goods,whether in preparation, spinning, or twisting, great inconvenience is brought about by the breaking of the threads or meshes. In the first place, there is the waste of material caused by the continuance of the feeding forward of the thread by the feeding-cylinder after breakage has taken place, so that the materialdelivered between the time of breakage and of reat tachment is Wasted; secondly, the thread or mesh can become rolled around the feeding cylinderanrl produces whatis called a knot, which causes great waste either by the deterioration of the material or by the thread becoming entangled in the neighboring threads and causing them to break; but the greatest inconvenience is caused when the broken thread becomes united with a neighboring thread, forming what is called a marriage. The double thread formed in this way does great harm to the texture and occasions great waste.

In order to avoid the above inconveniences, I employ the device which forms the subject of this application, which is so constructed that when a thread or mesh breaks the feeding-cylinder stops and revolving no longer the delivery of the thread ceases.

In the drawings, Figure 1 is a front View showing the parts in operative position. Fig. 2 is an-end view of the same. Figs. 3 and 4 are similar views,respectively showing the position the parts assume when a thread breaks.

The parts of this device are for each spindle as follows: first, a clutch-cylinder M, loosely mounted on the shaft A, carrying a projection C on one end and having its end cut in the form of a portion of a spiral; second, a helical spring R, encircling the shaft and abutting between the cylinder M and a driving-collar B, rigidly secured tothe shaft A and carrying a projection D, and, third, a lever F for guiding the thread, pivoted on a bolt E parallel with the shaft A and having at its front end a fork or claw f for guiding the thread and at its rear end a counterweight f. It carries also at its center a projection T.

The device operates as follows: hen the loom is working, the spring R pushes the clutch M against the collar B, producing the engagement of the tenons or projections O D, which are on the clutch and the collar, and therefore the rotation of the clutch-cylinder M. The threadwhich is delivered between the clutch-cylinder and the pressure-roller G passes over the guiding-fork f of the lever and by its tension inclines the latter in a forward position, as shown in Figs. 1 and 2. If the thread breaks, the lever being otherwise unrestrained swings backward and brings its projection T against the helical end of the clutch M. This latter continuing its rotation, is forced endwise and ceasing to receive its movement from the collar 13 it therefore stops turning and delivering the thread. In order to put into action after having reattached the thread, it is sufficient to rest the thread on the fork of the lever.

I claim- A stop-motion for spinning-machines, consisting of a rotatable shaft, a feed-cylinder loosely mounted thereon, a pressure-roller cooperating with the feed-cylinder, a collar fixed on the shaft and having a driving projection, a lug on the adjacent end of the feed-cylinder having a spiral face, a spring to keep the lug in engagement with the projection, and a pivoted lever having a projection to engage with the spiral on the lug and cause the cylinder to slide axially on the shaft, said lever being normally held out of engagement by the thread passing between the cylinder and the roller.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUSTE LEPOUTRE.
